I just tried with 128M, 64M, 512M and without any options.
In every case, it used 114M of ram, and took about the same length of time.
I think I may have made a typo when i said 214M before. Also, that the
-Xmx512M option isn't being passed through.
Also that I should have written EXPORT in the script. Oh dear.
Running that all again..
Now it's matching the sizes up, and there's maybe a fraction of a second
difference.. Like 250ms or so.. it's hard to tell, since that's about
the error margin for the tests anyway, but running them over and over I
think the average is a tiny bit higher.
That was with the 64M option, since the 128m was actually higher than it
was using, just..
